Implementation Reference
- src/operations/export.ts:52-78 (handler)Core implementation of the export_to_png tool. Validates the drawing ID, fetches the drawing data, and returns a base64-encoded PNG image (placeholder for real Excalidraw API export).
export async function exportToPng( id: string, quality: number = 0.92, scale: number = 1, exportWithDarkMode: boolean = false, exportBackground: boolean = true ): Promise<string> { // Validate the ID for security validateFileId(id); try { // Get the drawing const drawing = await getDrawing(id); // Return the PNG content as a base64 string // Note: In a real implementation, we would use the Excalidraw API to convert the drawing to PNG // For now, we'll just return a placeholder return "data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAEAAAABCAYAAAAfFcSJAAAADUlEQVR42mP8z8BQDwAEhQGAhKmMIQAAAABJRU5ErkJggg=="; } catch (error) { if (error instanceof ExcalidrawResourceNotFoundError) { throw error; } throw new Error( sanitizeErrorMessage(error, "Failed to export drawing to PNG") ); } } - src/operations/export.ts:12-18 (schema)Zod input schema for the export_to_png tool, defining parameters like id (required), quality, scale, dark mode, and background options.
export const ExportToPngSchema = z.object({ id: z.string().min(1), quality: z.number().min(0).max(1).optional().default(0.92), scale: z.number().min(0.1).max(5).optional().default(1), exportWithDarkMode: z.boolean().optional().default(false), exportBackground: z.boolean().optional().default(true), }); - src/index.ts:95-99 (registration)Registration of the export_to_png tool in the listTools handler, providing name, description, and JSON schema derived from ExportToPngSchema.
{ name: "export_to_png", description: "Export an Excalidraw drawing to PNG", inputSchema: zodToJsonSchema(exportOps.ExportToPngSchema), }, - src/index.ts:176-190 (registration)Dispatch logic for export_to_png in the CallToolRequest handler: parses arguments using the schema and invokes the exportToPng function.
